Abstract
The utility model relates to a Roots blower which belongs to the technical field of blowers. The blower comprises a motor, an impeller box and a gear box; a muffler extends from an air inlet of the impeller box; an oil dipstick seat extends from the wall of the gear box; the oil dipstick hole of the oil dipstick seat is communicated with the oil cavity of the gear box; the oil dipstick seat is provided with an oil dipstick; the oil dipstick goes deep into the oil dipstick hole and contacts with the oil cavity. The Roots blower has the advantages that ideal noise reducing effect can be achieved because of the muffler; the oil dipstick goes deep into the oil dipstick hole on the oil dipstick seat and contacts with the oil cavity of the gear box, so the oil dipstick is not damaged, does not need to be repaired and replaced, which is convenient for regularly or irregularly pulling out the oil dipstick to observe the oil status in the oil cavity of the gear box.
Description
Technical field
The utility model belongs to the blower technical field, is specifically related to a kind of Roots blower.
Background technique
The application of Roots blower is comparatively extensive, and for example textile industry can be used for dedusting, and for example cultures industry and can be used for to the oxygenation of the fishing pool, also as at sewage treatment industry, can be used for aeration oxygen replenishing, or the like.The action principle of Roots blower and structure substantially can be seen in pertinent literature such as Chinese patent literature in a large number, and be typical in Chinese patent notice of authorization CN2238925Y, CN2830714Y and CN2830716Y.The disclosed Roots blower of above-mentioned patent is not made the technology instruction to specifically how reducing noise.In addition, comprise the Roots blower in the prior art of above-mentioned patented technology scheme gear-box oil scale structure and be not content with actual application requirements, it is that the employing glass tube discloses the fluid situation in the gear-box, cause and to watch owing to the easy fragmentation of glass is difficult to change and is subject to the trifle in the world attack, thereby make the user whether be difficult to grasp in the gear-box oil starvation, in case and gear-box oil starvation and even oil-break then can cause the whole damage of gear-box.
Summary of the invention
Task of the present utility model be to provide a kind of noise reduction sound effective value desirable, can ensure reliably and grasp gear-box whether oil starvation or the oil scale freedom from repairs of oil-break and the Roots blower of free of replacement.
Task of the present utility model is finished like this, a kind of Roots blower, it comprises motor, impeller casing and gear-box, received a baffler on the suction port of described impeller casing, extended an oil ga(u)ge rod support on the wall body of described gear-box, the oil scale hole of oil ga(u)ge rod support communicates with the oil pocket of gear-box, is equipped with an oil scale on the oil ga(u)ge rod support, and oil scale is deep in the described oil scale hole and with described oil pocket and contacts.
The inwall of oil ga(u)ge rod support described in the utility model is provided with internal thread, and is processed with outside thread on the described oil scale, and outside thread matches with described internal thread.
The material of oil scale described in the utility model is a metal.
Compared with the prior art the technological scheme that the utility model is recommended has desirable noise reduction sound effective value owing to be provided with baffler; Contact because oil scale is deep in the oil scale hole on the oil ga(u)ge rod support and with the oil pocket of gear-box, so oil scale can not cause damage, need not maintenance and change, and be convenient to the interior fluid situation of oil pocket of transfering to oil scale to watch gear-box regularly or aperiodically.
Description of drawings
Accompanying drawing is a concrete real example structure figure of the present utility model.
Embodiment
Ask for an interview accompanying drawing, motor 1, impeller casing 2 and gear-box 3 jointly are fixed on the frame 5, fast pulley 111 on the output shaft 11 of motor 1, drive the gear shaft belt pulley 36 that is stretched over gear shaft one end outside the impeller casing 2 by belt, the other end of gear shaft is positioned at the case chamber of gear-box 3, and be fixed with gearwheel 35, gearwheel 35 drives the gear shaft (not shown) that impeller is housed.Casing top at gear-box 3 is provided with oil filler 32, and side bottom is provided with drain oil 33.The technological points of the technological scheme of recommending as the utility model is: at the top middle part of impeller casing 2 (the industry custom claims air pump) baffler 4 that is formed with inlet hole 41 is set vertically, be incorporated in the impeller casing 2 by the inlet hole 41 of baffler air, and then draw by the air outlet hole 2 that is opened in impeller casing 2 sidepieces with the external world.Be processed with an oil ga(u)ge rod support 34 below a lateral deviation of the width direction of gear-box 3, constitute oil scale hole 341 on the oil ga(u)ge rod support 34, this oil scale hole 341 communicates with the oil pocket of gear-box 3.In oil scale hole 341, be inserted with a material and be preferably the oil scale 31 of metal, preferred scheme is that the inwall at the position, aperture in oil scale hole 341 processes internal thread, process outside thread 311 in the upper end of oil scale 31 therewith suitablely, oil scale 31 can be inserted in the oil scale hole 341 reliably with cooperating of internal thread by outside thread 311.Compared with the prior art, oil scale 31 can not destroyed, therefore can use for a long time and need not maintain and replace, during oil level situation in will watching gear-box 3, as long as unscrew oil scale 31 and it transferred to oil scale hole 341, and then the fluid vestige on the observation oil scale 31, if the oil pocket oil starvation of gear-box 3 then replenishes by oil filler 32.
During use, can connect corresponding pipeline such as pvc pipe on air outlet hole 21, the air of the air outlet hole 21 of impeller casing 2 being drawn by pvc pipe causes field of employment for example the fishing pool or aeration tank etc.When motor 1 work, by gearwheel 35 work that are nested with the belt driven gear case 3 on belt pulley 111 and gear shaft belt pulley 36, and then make the impeller work that is located on the impeller shaft by the impeller shaft in the gearwheel 35 impeller casees 2 rotation, air is introduced from the inlet hole 41 of baffler 4, draws from the air outlet hole 21 of impeller casing 2.
Through the claimant Roots blower in Roots blower of the present utility model and the prior art is contrasted (rotating speed is all 1600n/min), noise can reduce more than 3 times, particularly oil scale 31 is reasonable in design, need not to carry on a shoulder pole to disturb the dust invasion and attack of suffering fragmentation or suffering application places.
